The body of David McAdory, 63, of Mississippi's Madison County was discovered near his anchored boat in the Chandeleur Sound.
Agents had been searching for McAdory since late afternoon Saturday, and found the anchored boat with fishing lines still in the water with no one aboard. They searched until nightfall with the help of a U.S. Coast Guard helicopter.
McAdory's body was discovered without a personal flotation device in 8 to 10 foot of water. Agents transported the body and McAdory's vessel to the Fort Beauregard landing, where the St. Bernard Parish Coroner assumed custody of the body to determine a cause of death.
LDWF agents do no suspect foul play at this time, as the victim suffered from an unspecified medical condition that could have contributed to his death.
